Neil Shuttleworth，an 82-year-old English man，was hardly able to walk because of osteoarthritis（骨關(guān)節(jié)炎） in his right ankle.Problems began for Neil after he accidentally stepped into an unseen hole in a road surface while on holiday in Cyprus several years ago.Thankfully，he received an artificial ankle made from the materials of bulletproof（防彈的）vests.
    Neil，who is a retired printing specialist from Huddersfield，West Yorkshire，paid for the operation himself since it is not currently available on the National Health Service（NHS）.When he finally chose to have the operation，he said it was because he had just one strong desire：to walk hand-in-hand with Christine，his wife of 34 years. "Actually，I wasn't expecting to run a marathon.I would like to walk down the Promenade de la Croisette in Cannes with my wife，but without the pain I had lived with for far too long，" Neil said.
    The operation uses polyethylene（聚乙烯）materials that are used to make bulletproof vests，but with extra added vitamin（維生素）E.Since the E-poly is made from strong plastic fibers，it is expected to last much longer than current replacements.
    Before he was injured，Neil had always led an active lifestyle which involved running and cycling across the UK and Europe.After he stepped into the hole，which was several inches deep，he said he could not walk more than a few hundred yards as the pain in his ankle was so excruciating.Neil is now one of the first patients in the UK to have such an ankle replacement operation.
    After wearing a special walker boot for six weeks following his operation，Neil received a strict six-week treatment that adopts special exercises.He is now able to walk a couple of miles，and he uses a running machine in order to build his fitness levels even further. "The results of Neil's operation are impressive and there is at least an 80 to 90% chance the ankle replacement will survive for 10 to 15 years，" said Professor Nick Harris，who performed the operation.
